摘要： A model structure modeling a power amplifier is based on at least a binomial expansion, a first building block, a second building block, and a third building block. The first building block is a first complex sub-band signal with a first delay, the second building block is a multiplication of the first complex sub-band signal with a second delay and a complex conjugate of the first complex sub-band signal with a third delay, and the third building block is a multiplication of a second complex sub-band signal with a fourth delay and a complex conjugate of the second complex sub-band signal with a fifth delay. The sum of the first complex sub-band signal and the second complex sub-band signal is a baseband signal. Terms are obtained by optimizing delay combinations for the model structure. The model structure is used to dual-band digital pre-distortion of the baseband signal.
